Water Dynamics in Microemulsion Droplets. A Nuclear Spin Relaxation Study

Carlström, Göran LU orcid and Halle, Bertil LU (1988) In Langmuir 4(6). p.1346-1352
Abstract

The state of water in aqueous microemulsion droplets in the system AOT/D2O/isooctane has been investigated by 2H and 17O NMR. Longitudinal relaxation rates are reported as a function of droplet size, droplet volume fraction, temperature, and resonance frequency. We conclude that the surface-induced perturbation of water rotation is of short range (limited to the primary hydration of the AOT head groups) and of modest magnitude (less than a factor of 10 slower rotation than in bulk water).
